USER MANUAL RoomMatch BOSE
Installation and Safety Guidelines
This product is intended for installation by professional installers only! Thank you for selecting Bose® RoomMatch™ subwoofer for your sound reinforcement system. This document is intended to provide professional installers with basic installation and safety guidelines for Bose RoomMatch™ subwoofer in typical fixed-installation systems. Please read this document before attempting installation.

WARNING: All Bose® products must be used in accordance with local, state, federal and industry regulations. It is the installer's responsibility to ensure installation of the loudspeakers and mounting system is performed in accordance with all applicable codes, including local building codes and regulations. Consult the local authority having jurisdiction before installing this product.

WARNING: Unsafe mounting or overhead suspension of any heavy load can result in serious injury and equipment damage. It is the responsibility of the installer to evaluate the reliability of any mounting method used for their application. Only professional installers with the knowledge of proper hardware and safe mounting techniques should attempt to install any loudspeaker overhead.
Guidelines for Permanent Installation of RoomMatch™ Subwoofer
The installation information contained in this document is only a general guideline and cannot, as such, represent all requirements and precautions. Accordingly, anyone using this material assumes all liability and is expressly responsible for the safety of all loudspeaker array designs and mounting configurations applied in practice.
1) Prior to the installation of any overhead loudspeaker, a licensed professional engineer must approve the location and method of attachment to the building structure and confirm they are consistent with all building codes and regulations. Ensure the mounting surface and the method of attaching the loudspeaker system to the surface is capable of supporting the total weight of the system. A safety factor of 10:1 is recommended.
2) Obtain all mounting system components from reputable manufacturers. Select a mounting system appropriate for your loudspeaker system and its intended application. We recommend Bose mounting accessories when available. A licensed professional engineer must review the design and fabrication of custom mounting hardware or alterations.
3) The top, bottom, and sides of Bose RoomMatch™ subwoofer features M10 threaded inserts to facilitate the suspension of the loudspeaker by a qualified person. Do NOT use SAE 3/8" size threaded hardware! Use only SI Class hardware. Fasteners should be SI Class 10.9 or equivalent. Unmarked fasteners should not be used. Use a minimum of four threaded-insert suspension points per loudspeaker.
4) Do not suspend loudspeaker using handles as attachment points. Handles are NOT designed for load bearing!
5) Use lock washers or a locking compound intended for hand disassembly, such as LOCTITE® THREADLOCKER BLUE 242® compound, for a vibration resistant assembly.
6) Fasteners should be long enough to engage no fewer than 14 full threads of the attachment point. Using a fastener that is too short may result in an unsafe assembly. Confirm that at least 14 full threads are engaged.
7) Fasteners should be tightened using torque not to exceed 35 to 40 foot- pounds (47 to 54 Newton-meters). Over-tightening the fastener could result in irreparable damage to the cabinet and create an unsafe assembly.
8) Do not attempt to alter the threaded attachment points or re-thread the attachment points to accommodate any other thread size or type; doing so will compromise the safety while permanently damaging the loudspeaker.
9) Use a safety cable, separately attached to the cabinet, at a point not in common with the load bearing attachment points of the mounting system to the loudspeaker. This is recommended even if not required by local regulation. Consult a licensed professional engineer or a rigging professional for proper design and installation.

CAUTION: Installed loudspeaker arrays require regular inspection and routine maintenance to ensure proper function and safe operation. Inspect mounting hardware and attachments for signs of corrosion, bending or any other condition that may decrease the structural integrity. Immediately replace worn or damaged components.

CAUTION: Make no modifications to the loudspeakers or mounting accessories. Unauthorized alterations may compromise safety and could result in damage, injury, or death.

CAUTION: The total weight of all suspended loudspeakers and rigging attached to the threaded inserts must not exceed the total Working Load Limit: RMS215 WLL = 510 lbs (231 kg).

Connector Wiring
The RoomMatch™ subwoofer is equipped with two (2) Neutrik® NL4 connectors wired in parallel to allow loop-through connection to an additional subwoofer. The connector is factory wired to provide discrete amplifier channel drive to each of the woofers as follows:
| NL4 Connector Pin Driver Bandpass Section | |
| 1+ Driver-1 positive | |
| 1 - Driver-1 negative | |
| 2+ Driver-2 positive | |
| 2 - Driver-2 negative |

Recommended Amplifier Power
Each 15-inch transducer of the RMS215 subwoofer features a long-term power-handling rating of 500 watts, with a transient peak rating of 2,000 watts. Selecting the proper amplifier size for a given loudspeaker requires analysis of the transducer long-term (or RMS) power rating, dynamic range of the input-source material (crest factor), desired sound pressure levels, and other factors. As a general guideline, to maximize the performance of the RMS215 subwoofer, we recommended using two (2) channels of amplifier power, each rated to deliver 1,000 watts into a nominal 8-ohm load.
| RMS215 Transducer Nominal Impedance Amp Channel Amp Power Rating | ||
| Driver-1 8 ohms 1 500 to 1000 watts | ||
| Driver-2 8 ohms 2 500 to 1000 watts | ||
The Bose® PowerMatch™ PM8500 Professional Amplifier (sold separately) is easily configured to provide the recommended amplifier power for the RMS215 subwoofer. It also provides presets for recommended signal processing, including several cardioid bass array settings.
Recommended Signal Processing
Digital signal processing (DSP) equipment is required for infrasonic protection, crossover, equalization, and protection limiting functions. The recommended processing for subsonic protection is a high-pass filter with center frequency of 40Hz and a roll-off slope of at least 12-dB per octave (2nd order filter).
The recommended crossover frequency for the RMS215 subwoofer ranges from 80Hz to 200Hz , depending on the response of your mid/high-frequency loudspeaker system. In general, we recommend using 24-dB per octave (4th order filter) crossover slopes between the RMS215 subwoofer and your mid/high-frequency system.
The Bose ControlSpace ESP (sold separately) provides presets for the RMS215 subwoofer and provides all required digital signal processing, including processing for several cardioid bass array configurations.
Attaching Bose RMSFLY Side-Plate Rigging Kit
The RoomMatch™ RMS215 subwoofer is shipped with no array rigging hardware. The optional RoomMatch™ RMSFLY accessory part (343856-0110) is available to facilitate integration of the RMS215 subwoofer in RoomMatch™ Arrays. The RMSFLY side-plate hardware is not required for floor or ground-stack installations of RMS215 subwooers. To attach the RMSFLY side-plate rigging hardware to the RMS215 subwoofer, follow these steps:
1) Remove RMS215 subwoofer from the shipping carton, remove packing materials, and place the subwoofer on the floor beneath planned suspension point.
2) Remove the eight flat-head screws using a 5.5mm hex key on the left and right sides of the subwoofer (four per side). Included foam washers under the inserts should remain affixed to the subwoofer.
3) Insert M10 x 40 mm fasteners through individual side-plates, and supplied flat washers, and then into the subwoofer inserts, tightening by hand as shown in Figure 2. Note the Left and Right part markings for side-plates. After both side-plates are attached, the RMS215 subwoofer is ready for integration with other RoomMatch™ modules in full-range arrays.
4) Attach the subwoofer/side-plate assembly to its associated array frame or upper subwoofer and tighten bolts by hand to facilitate alignment. After all bolts are in place, perform final tightening using torque not to exceed 35 to 40 foot-pounds (47 to 54 Newton-meters).
NOTE: U-Shaped side-plate channel faces upward, the raised mounting bosses face the cabinet, and the oblong alignment slot at the base of the side-plate points toward the front of the loudspeaker.
